In Semantic Mastery's Hump Day Hangouts episode 66, a viewer asked about creating multiple local listings to different cities within a metro for a storefront with only one physical address.
The exact question was:
I have a client with a store front that people can visit in one city – it's their one and only physical location. We want to get 3-pack listings in other cities in the metro area surrounding this location. We plan on using PO Boxes with street addressing so when we setup the GMB pages for these cities we would choose not to display the street address. We would also use different phone numbers for each GMB page. Does this make sense to do for a client? Are there any downsides to doing this??
